The superior cerebellar artery (SCA, Latin: arteria cerebelli superior) originates from the basilar artery. The SCA supplies the superior surface of the cerebellum and parts of the midbrain.
After it originates, the superior cerebellar artery runs laterally, winds around the cerebral peduncle of the midbrain to reach the upper surface of the cerebellum. Here the vessel divides into branches which ramify in the pia mater and anastomose with other cerebellar arteries. Several branches are distributed from the superior cerebellar artery to the pineal body, the anterior medullary velum, and to the tela choroidea of the third ventricle.
